"The finest glasses for both technical and hedonistic purposes are those made by Riedel. The effect of these glasses on fine wine is profound. I cannot emphasize enough what a difference they make."
(Robert M.Parker, Jr. The Wine Advocate)
I can also testify to the need for every wine lover to own a few Riedel stems. I own the bordeaux style Vinum stems myself and use the for all my reds. I will soon purchase some other style Riedel's for whites and so on. They are abit on the expensive side but well worth the money.
